To rut 1m 011/ M 11.1 a conccm:

Be it known that I, ALBERT C. Fnnnrnn, a citizen of the United States,residing at Lincdln, in the county of Lancaster and State of Nebraska,have invented certain new and useful Improvements in CarbureterAttachments, of which the following is a specification.

This invention relates to a carbureter attachment for internalcombustion engines useful for ponducting steam to the carbureter orintake manifold, from the radiator, to economize in the use of fuel andto prevent the formation of adhesions within the cylinders, and. also toreduce the temperature of the engine, and for one of its objects toprovide means ."which are effective and con'venie for: superheating thesteam. -Other objeets of the invention to means for a control of themovements of the superheated steam by an operator, so that it may enterthe carl'mreter, the intake manifold or may be prevented fromenteringeither of them. The invention incllugdes means which, operateautomatieaily' for permitting air from the at at to enter the carbureterupon certain dcasions when most needed, and also inclu es means formaking certain adjustments found tobe of advantage, and to such simplestructural parts that the device may be applied to engines readily atany time, or when constructed at the factory.

With the foregoing objects in view, the invention presents a novelconstruction, combination and arrangement of parts as described hereinand claimed, and as illustrated in thmaccompanying drawing, it beingunderstood that changes in form, size, proportion and minor details maybe made within the scope of the claim.

the drawing, Figure 1 is a partly broken view in side elevation of anntcrnal combustion engine in conventional 1 upon automobiles, showingthe device iii-ed thereto. Fig. is a side view of a lve employed. 1s asectional view 0 the valve housing. 4 is a transverse section on line"4: of Fig. 2. Fig. 5 is a. transverse section on line. 5-5 of Fig. 2.

Referring now to the drawing for a more particular description, iprovide a conduct 'ing pipe 6 having one of its ends 02 disposed in theupper part of the radiator 7 above upper end of the combined vent anddrain pipe 8, so that low pressure steam or moist air may be conducted.by the pipe, but that water will not enter therein, the opposite orlower end b of the pipe being at all times in communication with theintake port 9 of a casting or valve housing '10 for a conical valve 11seated therein. said valve being under control for rotation in eitherdirection by means of the inclined operating rod 12 secured thereto by asuitable key member 13, and pressed to its seat by the spring washer 14under control of an adjusting screw 15.

Numerals 1G and 17 respectively indicate the carburetor and its fuelsupply pipe. the conventional air intake chamber for the carburetorbeing indicated at 17. the supply of air generally being eon-trolled bya shutter, the lover of said shutter being indicated at 18. In thepresent instance this air intake is not employed and other means areprovided for supplying air to the carburetor. At :1: is indicated aspring which is connected with the lever 18, and which operates in amanner to prevent. air from entering the carburetor in the usual way, bypassing the shutter.

,The lower end of the valve housing is- 0 provided with a cylindricalcompartment 19 in eou'unlmieation with the conical valve seat by meansof a passageway 20 and in communication with the atmosphere by means ofsuitable intake ports 21 which are normally closed by a valve 22, thespiral spring 23 being pressed against this valve, and the tension ofsaid valve being adapted to be,

adjusted by the screw plug 24 which circumscribes the valve stem 25. Thevalve 11 is provided, longitudinally, with a recess 26, and also isprovided, to open upon recess 26, with a transverse recess 27. In orderthat the steam may attain a high degree of heat before entering thecarbureter, suitable apertures are formed in the exhaust manifold 28,and the conducting pipe (3 may therefore traverse it for a considerabledistance, as shown in the drawing.

An operator, by use of the shaft or red 12 may rotate the valve 11 sothat the recesses 27 and 26 which define its passageway, will registerwith the ports 9 and 20 of the valve housing, the superheated steamthereupon passing through the nipple 29 and entering the compartment 17from which it moves directly to the ,carhureter where it will becomemixed with the-gas, and the mixture of. gas and heated steam willthere-.

after-enter the intake manifold 30, with the result that the fuel willbe economized. The steam thus introduced also tends to prevent carbonfrom adhering to' the inner walls of Since the pipe 6 which conductssteam to the carbureter will not supply a SllfilOlGIlt quantity of airat all times, the tension of the spring 23 is so adjusted that, byoperation of suction, caused by the pistons in the engine cylinders, airfrom the atmosphere will enter the ports 21. It will become mixed withsteam and will enter the carbureter ih a heated condition to supply allof the air needed.v

In some instances it is desirable to introduce su. erheated steam to theintake manito'prevent it from passing through and means are provided forThe valve housing is proexjt port 31 and the intake this purpose. videdwith an manifold is constantly in communication 'with said port 31 bymeans of the and it will be seen valve 11 substantially position of pipe32, that, by rotating the a halfcircle from the .parts shown in Fig. 3,the port 20 will be closed and the steam ,will pass directly to theintake manifold, the valve 22 supplying air to the oarbureter. Also itwill be understood that the three-way valve 11 may be rotated in amanner to close the I port 9 and thereby to prevent any steam frompassing'said valve, this being desirable,

' when testing other parts of the engine, is

reouired.

second valve being provided with resilient Itfwill be understood that anoperator, by use of the rod 12, may so dispose the valve llthattheintake 9 will be entirely open .or partly closed, with the result thatsuperheated steam may freely enter or that only ai'limited' amount ofsteam will be admitted to the; intake manifold or to the carbureter.Having fully described construction, a

further explanation relating to operation-is, I. .50

not necessary.

What I claim as my invention and desire to secure by Letters Patent'is,-

Devices for the purpose described, 'com prising, in combination with theintake manifold, the radiator, the exhaust manifold and the carbureterof an internal, combust'ion engine, a conducting pipe traversing a' partof the exhaust manifold and communicating with the radiator, avalvehousing provided with a compartment communieating with thecarbureter and also provided with an air intake, a valve in the valvehousing, said valve being movable to permit a communication between theconducting pipe and said compartment, a second valve, said means fornormally causing a closure of said an intake and adapted to have a.movement to permit air to enter said compartment,

said first named valve being also movabllfm for terminating thecommunication of tlf to conducting pipe with said compartment andpermitting a communication of the conducting pipe with said intakemanifold. I
